MEANS FOR ATTACHING DEMOUNTABLE RIMS.

Specification of Letters lPatcir'c.

thanthe wheel rim and 12 a tire. l have illustrated the application the invention in connection with the well known cleneher tire rim, so called. it should be understood however. that the special form wheel rim and the special make of tire rim are wholly 1 immaterial so far as the present invention is concerned.

My novel attaching means coir-g sts simply of a plurality of bolts, for exai'nple ordinary carriage bolts, lying lie-tween the rims and two specially formed clamps carried by each bolt which are adapted to engage boti the To all whom it may con-corn:

.Be it known that I. HARRY H. Form, a citi i zen of the United States, residing at lh'idgcport, county of Fairfield, State of Couueciicut, have invented a new and useful filoans j for Attaching Demountable Rims, of which i the following is a spccilicfition.

This invention relates to the class of vehicle wheels, more especially automobile able tires, that is tires which may be carried already inflated and attached to tire rims so that should a tire give out in use the tire rim and tire may be readily removed from the rim of the wheel and a new tire already inflated and attached to another tire rim may be substituted in its place, thus making the task of replacing a tire on the road a simple operation and one that can'be quickly formed by any person not necessarily amechanic and without the use of special tools The present invention has for its objects to provide simple and inexpensive means for detachably securing tire rims to any wheels having metallic rims and to provide open air space between the tire rim and the wheel rim for the purposes of keeping the tire rim and tire cool of preventingthe tire rim from becoming set on the Wheel rim by oxidation and of permitting an ordinar tion at the bolt under the head and the other standard valve stem to be inserted in and with a hole through which the bolt passes withdrawn from the hole in the wheel rim .iilaeh clamp provided ii its inner face and telly in mounting or demounting a tire with a. socket which l l to receive, without danger oi, injury to th valve stcm the on the 'l'ii v'ith these and other objects in vie V securely. l have devised the novel tire rim atta irovided iv e 1 means. of which the following :c i 1 pass under and in connection with the accompanying ti oi? the wheel. ings is a specification reference charac being used to indicate the several parts.

'lhis air space between the means for preventing the tire rim from t e rim and the wheel rim is a matter of creeping on the wheel rim; and Fig; -l is a r l importance as it a to a marked dsectional View illustrating the operation of gr o cool the L rim and the tire, the mounting or demounting a tire rim and tire, rotation of the wheel causing a co: taut cir the bolts and clamps being removed. culation of air between the two runs. An-

denotes the rim of an automobile wheel other important at" ntage resulting from 11 a tire rim of appreciably greater diameter rigidly scouring the we rim out of contact,

tire rim and the wheel riin and secure said' with the wheel rim is that all danger of the two rims becoming set together by oxidation is avoided. And a third important ad vantage resulting from providing an appreciable space between the rims is that in de mounting a tire it permits the portion of the tire rim and tire opposite to the valve stem to be swung forward, as clearly shown in Fig. 4, after which the tire rim and tire may be raised and the valve stem drawn out of the hole in the wheel rim and telly without the slightest difiiculty. The same advantage results in mounting a new tire rim and tire. I

The operation. will be obvious from the drawings. The tire rim is placed over the wheel rim and a plurality of bolts passes between them, clamps provided with angular openings having first been placed. upon the bolts. The sockets are then placed in engagement with the face of the tire rim and the lips under and in engagement with the wheel rim. The other clamps are then passed over the threaded ends of the bolts, the sockets receiving the other face of the tire rim and the lips passing under and engaging the other edge of the wheclrim. The two rims are then rigidly secured together with the air space between them by means of the nuts.

In order to prevent the possibility of the tire rim and tire creeping or sliding upon the Wheel rim, I provide suitable means for locking the tire rim against longitudinal movement. This may be accomplished in any suitable manner. In the present instance I have shown a plate 23 which is secured to the innerwall of the tire rim by rivets as at 24;. This plate is provided on said bolts which engage said rims respectively and secure them rigidly, to each other, the clamps having inwardly extending lips engaging under the wheel rim and having portions engaging both inner and outer portions of the tire mm to hold the tire rnn 81380011 from the wheel mm.

In testimony whereof I affix my signature, in presence of two witnesses.
